Good standard rack for suit your needs for 3 units.
My only complaint is the angle. Due to that, the lowest slot is suitable for powerstrip or patchpanel etc. but due to angle, most rack model audio equipement is too deep for it.
Also first slot on the top is designed for rack light like <a class="article link" href="https://www.thomann.de/fi/adam_hall_87451_pro_c_led_rack_light_mc.htm">Adam Hall 87451 Pro C LED Rack Light mc</a>, so it really has slots for 4 units, 1 racklight and 1 patchpanel or powerstrip.
Other than that the build quallity is very good. parts won't bend easilly (even the support pipe on top is surprisingly sturdy), rubber feets are top notch, it almost feels like my rack is bolted to my table.
Overall good rack, but due to the design I would recommend this to be used for powerstrips, patchpanels etc. because it really seemes like that's what this is for, to be left on the floor or stage with some patch panels or powerstrips or cable management.
